## Description
Replace the PDF renderer with an custom image renderer.
This allows us to remove the "react-pdf" dependency and allows us to use
a virtual list to improve performance.
Add fullName prop to signature pad components to automatically populate
typed signature
field with signer's name. Updates signature dialog, type component, and
all signing forms
across embed, document, template, and envelope flows to pass through the
user's full
name for better user experience.
This PR is handles the changes required to support envelopes. The new
envelope editor/signing page will be hidden during release.
The core changes here is to migrate the documents and templates model to
a centralized envelopes model.
Even though Documents and Templates are removed, from the user
perspective they will still exist as we remap envelopes to documents and
templates.
